Filed: 1988-04-28
Abstract: PURPOSE:To obtain an antenna system having two radiant waves by providing another primary radiator around a sub reflection mirror and displacing the fitting position of this primary radiator around the sub reflection mirror. CONSTITUTION:The wave radiated from a first primary radiator 3 is reflected by a sub reflection mirror 2 and a main reflection mirror 1, after that, it becomes an equiphase plane wave on the opening face of the main reflection mirror 1 and is radiated in the direction shown by broken lines. On the other hand, a second primary radiator 4 is provided around the sub reflection mirror 2 and the radiant wave from the radiator 4 is radiated in the direction shown by alternate long anf short dash lines 42. The angle of the difference between the directions of a first radiant wave 32 and a second radiant wave 42 is fixed by a fixture after the position of the radiator 4 is so selected that it may be equal to the difference between the directions of two desired satellites to be directed and thus, the two-satellite directivity can be realized.

Title: Optical fiber connector
Inventor: SAITOU MASAMITSU
IPC: G02B6/38
Filed: 1978-09-04
Abstract: PURPOSE:To obtain an optical fiber connector not requiring processing of high precision, by using a fitting hole and three columns. CONSTITUTION:A columnar plug 3 having an optical fiber 2 disposed in the central axis position is inserted into a sleeve 1 having a fitting hole 4 of a relatively loose precision and three columns 5, and connected. A leaf spring 6 to hold the three columns 5 is provided on the outside of the sleeve 1.
